Change subject: IMPALA-13107: Don't start query on executor if instance number equals 0 ...................................................................... IMPALA-13107: Don't start query on executor if instance number equals 0 In bad networking condition, TExecPlanFragmentInfo in KRPC messages received by executors could be truncated due to KRPC failures, but truncation may not cause thrift deserialization error. The invalid TExecPlanFragmentInfo causes Impala daemon to crash. To avoid crash, query with number of instances as 0 should not be started on executor. Testing: - Passed core tests.
